What's Happening Here?

1. When right clicking on an analysis and clicking/Backfill/Recalculate data, the following error is displayed: (See BackfillError1.png) 2. If we change the file name of the PIRecalculationProcessor.exe to PIRecalculationProcessor.exe.config.old, the following message is displayed when we attempt to backfill/recalculate and never clears…(Show moreShow less)

Hello All, We are developping a Data Quality product, that should be capable to detect stale Tags. So, first, here is our definition of stale: A Tag will be detected as stale if for a certain period of time, the number of reported values by the Tag will be lower than a minimum threshold. We capture (with AF SDK) the last value of the tag…(Show moreShow less)

If you have tags that are NOT being actively populated by design, then, yes, you can have tags that are not receiving values and are not in error. Examples: lab tags without an active input source; the tag has a fixed value or is manually entered analyses that are event based, but the triggering event never receives a value

It was possible to extend the functionality of earlier versions of PI-AF by writing your own Data Reference functions. Will something similar be available for Analytics? Can we extend the available functions with user written ones?

Hi, In PI connectors of OPC UA, is it possible for change the existing environment setup of OPC DA to OPC UA structure without affecting the Existing PI tags. kindly let me know any approach for migrate the OPC DA to OPC UA.

They do not necessarily have to be in the same domain. There are some considerations that you can look into for cross domain Kerberos. Please see this link. KB01709 - Kerberos Delegation across multiple domains

Hi, We re-installed PI Data Archive and Pi AF server using PI-Server_2018 installer. After installation few services are missing, PI AF Link Subsystem PI Performance equation schedular PI batch generator PI Recalculator subsystem So we are not able to connect to AF server When we try to run PI MDB to AF preparation wizard we are getting…(Show moreShow less)

Hi everybody, I'm face to the following case. We would like to retrieve data from ou entire SCADA/PCS/DCS/... into OSI-Pi. For the time series, it will not be complicate because the data willbe stored as OSI-Points. But the question is what to do with "non time series" data like : - Alarms. - Audit trails. - Batch execution data. -…(Show moreShow less)

If you store it in a SQL Table, you could use Table Lookup Data Reference to bring it into AF as AF Attributes. From there, PI Vision will have the native capability to display these AF…

We have a question about the attribute properties drop down in AF. In particular, we would like to better understand the use of “Configuration Item” flag. We can read from the definition that this flag indicates that any attribute edited having this flag requires there to be a check in. My question is, what was the motivation behind this flag and…(Show moreShow less)

Steve, This is an interesting idea. However, as a general rule we tend to not want to create elements unless they tie to an actual asset or other structure we are trying to model. For now we have decided to create a category called “Device Parameter”. The CMS client will know what to do with this parameter (ready only) and as an added bonus…

I just read this article and found it quite interesting: Will the Data Historian Die in a Wave of IIoT Disruption? A lot of traditional IT companies (Microsoft, IBM, etc) are on the move into the cloud, and although we all know that a time series database is the best location for time series data, it's no doubt that they will be trying to…(Show moreShow less)

I am interested in recommendations or proven setups for implementing Virtual PI Development System. I want to have the following applications within the system. PI Server, ProcessBook, DataLInk, BatchView, PI Vision, AF, Active View, and PI Manual Logger. I am sure there is a "best practice" available somewhere and I definitely want to leverage…(Show moreShow less)
